Application inea June 30,1896. serial 110.597,59?. (Nomad.)

4To all whom t may concern.-

Be it known that I, GERHARD B. OsTDIEK, a citizen of the United States,residing at Neola, in the county of Pottawattamie and State of Iowa,haveinvented a new and useful Forceps, of which the following is aspecification.

My invention relates to forceps, and has for its object to provide meansfor facilitating the connection and disconnection of the membersthereof.

Further objects and advantages of this inl vention will appear in thefollowing description and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings, Figure l is a perspective view of a pair of forcepsconstructed in accordance with my invention, the members beingconnected. Fig. 2 is a similar View showing the members disconnected.Fig. 3 is a detail view of the pivotal securing-plate or latch inverted.

Similar numerals of reference indicate corresponding parts in all theiigures of the drawings.

The forceps consist of detachable members l and 2, provided at theirpoint of intersection with flat bearing portions provided, respectively,with an opening or bearing 3 and a fulcrum-pin or stud 4.. Pivotallymounted upon the shank or handle portion of the member 2 is asecuring-plate or latch 5, the same having an enlarged iat head 6, whichcovers the exposed end of the fulcrum-pin or stud when turned to theposition illustrated in Fig. l. This securing-plate or latch ispreferably mounted upon a fixed pivot 7 and is extended beyond saidpivot to form an operating extension or arm 8, which may be pressed bythe thumb of the operator to move the securing-plate into either itsoperative or inoperative position. This rear end or extension of thesecuring-arm is Within convenient reach of the thumb of a hand graspingthe handle.

The device embodying my invention is particularly adapted for use asswine-forceps wherein it is desirable to provide means for positivelysecuring the members in their operative positions, and from the abovedescription it will be seen that by the use of the latch the parts maybe connected or disconnected without loss of time and with the leastexertion upon the part of the operator.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the spirit orsacrificing any of the advantages of this invention.

Having described my invention, what I claim is- 1. Forceps havingseparate members adapted to be overlapped at their fulcrum-points andprovided, respectively, with av fnlcrumpin and an opening adapted toreceive said pin, the pin being adapted to extend through to the outersurface of the member having the opening, and a securing-plate or latchpivotally mounted upon the member carrying the fulcrum-pin and adaptedto be terminally arranged over the member having the opening to bearupon the extremity of said fulcrum-pin,whereby detachment of the membersis prevented, except when the securingplate or latch is deiiected toremove its `free extremity from engagement with said fulcrnm-pin,substantially as specified.

2. Forceps having separate members adapted to be overlapped at theirfulcrum-points and provided, respectively, with a fulcrumpin and anopening to receive said pin, said pin being adapted to extend through tothe outer surface of the member having the opening, anda securing-plateor latch pivotally mounted at an intermediate point upon the memberhaving the fulcrum-pin, and adapted to swing terminally over theoverlapping portions of the members, when connected, to bear upon theextremity of said fulcrum-pin and prevent accidental disengagement ofthe members, and having its oppositely-extending arm arranged Withinreach of the ngers of a hand grasping the handle of the member, wherebysaid securing-plate or'latch may be swung in either direction, to lockor release the members, Without removing the hands from the handles ofthe members, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two witnesses.

GERHARD B. O STDIEK.
